On an average work day I transfer between 20-200GB of data using my computer. Half of it is on a network connection that ranges between 10-13MB/s. That means that for the network portion I have a minimum of 13 minutes and a maximum of two hours where I can't do much else.

The other data transfer is from my computer to 10 to 20 USB 2.0 hard drives so that they can go and be happy Windows 7 Installation points.

USB 2.0 has a realistic maximum transfer speed of 30MB/s on large files. Up until today, this has been my only option because it was all that the hard drives I had supported. Each hard drive gets 14GB of files and averages 26MB/s for the whole transfer. This means that each drive I need to do takes 9 minutes.

If it is a day of 10 drives, that means 90 minutes, if it is 20, then 180 minutes.

What a waste of my fucking skills... this shit will give anyone brain rot and is a huge waste of time.

But today all of that is going to change. You see, today I was given USB3.0 cards for my workstations and USB 3.0 hard drives. The drives can support eSATA, USB2, USB3, and Firewire. But honestly, USB3 is the only one I need today.

So how fast can 14GB be transferred over USB 3.0?

Reading from the device, I was able to copy 14GB in: 5:40 (Average 41MB/s)
Large files sustained transfer speeds of ~60MB/s

Writing to the device, I was able to copy 14GB in: 3:47 (Average 62MB/s)
Large files sustained transfer speeds of ~90MB/s

My days just got a lot better.

USB 3 is the shit. If only someone could explain that to Intel the world's problems might all be solved.

The hell did this slip under my radar? Didn't even know USB 3 was coming out. Very exciting stuff though.

This looks good, but what will I need to do to upgrade? I've got a laptop; am I going to need to get a new one?

I'm assuming yeah, since everybody except maybe brand new ones will have USB 2.0

Well, actually I have been wanting to get a new computer, my current one (Acer Aspire 5935G) is kinda really rubbish (after all, who on earth would want a computer that crashes whenever it gets put into sleep mode or hibernate)

Native USB 3.0 won't be available from Intel until 2012.

Until then, you will need some form of card to support it unless the motherboard manufacturer pushes it to a specialized chip on the mobo. This is happening, especially on enthusiast equipment.
